PAUL VON STEITINA, OF SCHENECTADY, NEW YORK.

HORSESHOE.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed March 8, 1909. Serial No. 481,926.

To all whom it may concern:

Be it known that 1, PAUL VON STETTINA, a subject of Franz Joseph,Emperor of Austrial-Iungary, residing at Schenectady, county ofSchenectady, and State of New York, have invented certain new and usefulImprovements in Horseshoes, of which the following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

Figure 1 of the drawings is a view in perspective of an invertedhorseshoe provided with a toe-calk in accordance with my invention. Fig.2 is a bottom plan view of the toeportion of the same. Fig. 3 is avertical cross-section taken on the broken line 33 in Fig. 2, throughthe toe-portion of the shoe and the blunt or broad faced portion of thecalk. Fig. l is a similar section taken on the broken line 4 L in Fig.2, through the toe-portion of the shoe and the beveled or sharpenedportion of the calk.

The principal object of the invention is to overcome or correct by meansof a shoeattachment certain foot-faults common to many horses.

It is well known that many horses have a tendency to tread mainly withthe outer edge of the hoof, which faulty tread when long continuedinduces various defects and diseases of the foot and legs of the horse.

I have ascertained and demonstrated that this tendency can be correctedand overcome by a shoe-attachment in the form of a toecalk, which can bereaclily applied to, or farmed as a part of, the toe-portion of the s0e.

To render a shoe corrective of such a fault, I attach to, or form upon,the underside of the shoe a toe-calk extending substantially from oneside to the other of the toe-portion of the shoe, transversely of thelongitudinal axis of the shoe, which toe-calk is throughout its lengthof substantially uniform height or pro ection from the under face of theshoe, and has a blunt portion having a broad face extending from itsouter end approximately to the longitudinal axis of the shoe, and asharpened portion formed by a bevel or undercut on its front sideextending from its inner end approximately to the longitudinal axis ofthe shoe.

Referring to the drawings wherein the invention is shown in preferredform, 1, represents the shoe, which may be of any ordinary type, and, 2,is the toe-calk which projects downward from the toe-portion of theshoe, across which it extends in a direction transverse to thelongitudinal axis of the shoe.

The calk is of substantially uniform height or projection from theunderside of the shoe, from end to end, and it extends substantiallyfrom the outer side, 8, to the inner side, 4:, of the shoe, withrelation to the position of the shoe when in use upon the hoof of thehorse.

Substantially the outer half of the calk is blunt, having a broad, flatface or tread, 5, while the inner half of the calk has a sharp edge, 6,extending along its rear side formed by beveling or undercutting thefront side of the calk, as shown at, 7.

WVhen a horse having the fault of treading on the outer edge of the hoofis provided with a shoe having my improved toe-calk, the faulty positionof the hoof will cause the outer end of the toe-calk to first engage theroad-bed; but, as engagement of the extreme outer end only of the calkwill afford an unstable support, the hoof will tend to rock to a properor straight position, causing the sharp end of the calk to be broughtinto engagement with the road-bed. As a horse completes its step by adownward and rearward push with the toe of the hoof, it will find that amuch better purchase can be obtained with the inner sharpened end of thecalk than with the outer blunt end thereof.

Continued use of a shoe provided with such a calk will overcome thetendency to tread with the outer edge of the hoof, because the horsewill soon learn that by mak ing greater use of the inner edge of thehoof, a more effective purchase can be obtained, and that the rolling orrocking of the hoof due to instability of the support afforded by theblunt outer end of the calk will be avoided.

The shoe may be provided with a calk made in accordance with myinvention either by forming the calk integral with the shoe, orpreferably by welding to the shoe a separately made calk.

Vhat I claim as new and desire to secure side to form a cutting edgefrom its inner 10 by Letters Patent is end approximately to said axialline.
